Puerto Rico Case Resolution

All-domain Anomaly Resolution Office · 7 pages · text from the file's own layer

This All-domain Anomaly Resolution Office (AARO) case resolution, dated 20 March 2025, looks at infrared video recorded on April 26, 2013 by a U.S. Customs and Border Protection aircraft over Rafael Hernandez Airport near Aguadilla, Puerto Rico. Using reconstruction and pixel analysis, AARO found with high confidence that the two objects drifted over land at wind speed and never entered the ocean. It concludes with moderate confidence that they were a pair of sky lanterns.

Case Overview
On April 26, 2013, an infrared (IR) sensor
onboard a U.S. Customs and Border
Protection (CBP) De Havilland Canada 8
aircraft flying above Rafael Hernandez
Airport near Aguadilla, Puerto Rico
captured thermal video footage of two
objects drifting at wind speed and direction.
The objects appeared to move at a high rate
of speed over the airport and surrounding
area before separating from one another.
The objects seemed to enter, exit, and
disappear into the Atlantic Ocean off
Puerto Rico's northwestern coast.
During the encounter, the CBP aircraft flew
in an arc around the Rafael Hernandez
Airport, gaining approximately 1,725 feet
in altitude before losing sensor contact with
the objects at 3,600 feet. The aircraft
entered a layer of scattered clouds as it
passed 3,000 feet in altitude. These clouds
partially obscured the sensor's view,
potentially affecting the objects’ sensor
return. The range between the aircraft and
the objects nearly tripled during the
encounter. These factors contribute to the
